Four Cummins QSM60-M mains 2700 HP each @ 1900 RPM

The Alex F. McCall is equipped with three Cummins QSM11 powered 290-kW main generators. In addition to pumping and general ship’s needs these also power the three electric-operated 200 HP Thrustmaster tunnel bow thrusters for the DP-2 certified crew-supply boat.

Main engines are four Cummins QSK60-EPA Tier 3 (IMO Tier 2) compliant diesels each delivering 2700 HP at 1900 RPM. Each engine drives a Hamilton HT810 water jet to give the boat a 32-knot maximum speed. At a cruising speed of 26 knots (1800 RPM) the mains burn 366 gallons per hour. At the economy speed of 22 knots (1500 RPM) this drops to 264 gallons per hour.
